If you prioritize gaming features and response time, the LG C1 might suit you better, and it's usually less costly than the Sony A90K. However, for sports, the Sony A90K has a slight edge, especially in bright rooms, although it doesn't perform as well as the LG C1 in very bright conditions. Both have excellent performance in dark rooms and for watching movies or series, with the Sony A90K having a higher score for quality control. If sound is important to you, the LG C1 has a more powerful speaker setup. Both TVs support Dolby Vision and HDR10, but the LG C1 does not support HGiG or DTS:X, which are available on the Sony A90K.
